Video Summary
This video illustrates human population growth over the past 2,000 years. It corresponds the rising and falling of human population to major events in history such as the Roman Empire, the Black Plague, and the World Wars. Population growth as described by this video is relatively slow and steady from the Roman Empire through the discovery of the New World. Then, as modern medicine is introduced and the Information Age begins, human population increases dramatically.
Relevance
We spent some time in class discussing the population of an ecosystem, what affects it, and how it affects the way that an ecosystem functions. We touched upon human population and the question, "Why did the population grow so rapidly over the last 200 years?" We discussed that the reason for the dramatic increase in population was the advances in medicine and technology, the same way that this video correlates modern medicine and the Information Age to a rapid population growth.

Why are populations so concentrated in areas such as China, India, and Europe, rather than spread across the globe more evenly?
ReplyDelete(Also, how many people is 1 dot?)
Areas such as China, India, and Europe are areas where major civilizations developed. Human life is thought to have originated in Mesopotamia (modern day middle east, including parts of southern Europe and western Asia) and then humans traveled to settle in Europe, Asia, and Africa. It makes sense that populations are concentrated in these areas because that's where the major civilizations were.
DeleteIs our population expected to decrease like it did when the plague hit, or will our population continue to grow and spread?
ReplyDeleteSince we are unable to predict if/when major decreases in population will occur, our population is expected to grow.
